Finally got the right size! I ordered an XL at first and it buttoned but was too short. I then ordered an XL long that was the length we needed but then wouldnt button. Finally, I ordered a 2XL long and it was perfect! Arrived extremely fast however, when i got my refund they deducted $5 from my purchase. Not sure why. I will be contacting seller. Took a star away for that.Sizing on vests can sometimes be very hit or miss. I usually wear a medium t-shirt, and a 42-44 for coats. This fit me almost exactly the way I wanted it to. It is a bit dressier than I thought it would be, which is fine, but I do hope it breaks in a bit to feel more casual after some use.Nice material and excellent slim fit.I am 6'3 and 170 lbs.This is a decent vest other than the sizing. My husband is a L/XL and had to get the 2XL based off of other reviews and i'm glad he did. So size up!Nice vest good Quality.. but runs small so if you usually wear a XL..buy a XXL..i had to exchange the size because it runs smallOnce we got the right size it was perfect for the daddy daughter dance :) it’s pretty true to sizeMy stepfather loves this vest! It's lightweight and perfect for the summer. It was also very hard to find a vest that did not have an acetate back showing. This is linen front and back (acetate on other side of back to allow ease in slipping on.)Very nice vest. Linen all the way around. It is off white so lots of flexibility in what to wear it with. i read many reviews about the sizing being small so ordered an XL instead of my usual large. That was too big. I returned and they shipped out a large no questions. Very good purchasing experience.The fit is not as tailored as it looks in the picture. I bought it for my wedding and ended up not using it. Not a fan of the $10 shipping charge but I didn't really find many other options.
